Question

Write the photo chemical reactions which involves
1. Silver salt
2. Water

Answer 1

Photochemical reactions are those reactions which take place in the presence of sunlight .

1. 2AgCl(silver chloride) + (sunlight) → 2Ag + Cl2

2AgBr (silver bromide ) + (sunlight) → 2Ag + Br2

The silver halide is sensitive to light and in presence of light breakdown to form silver halides.

2. 6CO2 + 6H20 (water) + (solar energy) → C6H12O6 (glucose) + 6O2

This reaction is the process of photosynthesis.

Photosynthesis is the process by which plants and other organisms produce glucose and oxygen in presence of sunlight , carbon dioxide and water .
